T 1 all whom "it may concern:

Be it known that 1, Campus H. SAMPsoN, of Rochester,in the county of Monroe and State of New York, have invented a new and useful Improvement in Printing-Dies, which improvement is fully set forth inthe following specification and shown in the accompanying drawings.

The present invention relates "to printing dies and more particularly to that type in trim or breakthe paper in order'that an erasure of, the printed matter can. not be effected, such dies being generally used on what is known as check protectors or check November, 1911; and an object ofth'is invention is to provide a construction in which the dies are soformed that the printing surface maintains a fiat'face for the reception ofthe ink and thus gives a perfect impression even after the machine has been used a great length of time.

To these and other ends the invention consists inv certain parts and combinations of parts all of which will be hereinafter de-" scribed, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a side elevation, partly in section, of a machine constructed exactly like that shown in my Patent #1,010,1'80 with the exception that the improved dies, forming the subject matter of this invention, are employed; Fig. 2 is an enlarged sectional view in the direction of the printing line through both of the dies;

Fig. 3 is an enlarged lan view of the character die; Fig. 4: is an enlarged plan view of the platen die; and Fig. 5 is an enlarged view of a character printed by the printing printing position by a mechanism shown more fully in the before-mentioned patent.-

The present invention has to do with the printing dies. for a machine of this type or other constructions wherein the same objects or results are desirable.

The printing die is formed from soft metal with each character 10 projecting from the face of the holder or wheel 5. The

type to the other, in this instance, from the top to the bottom, and at an oblique angle to the height of. the, character, the depths of these grooves being not so great as the depths of the characters. The faces 12 of face of each character -is formed with the characters between the grooves ll-are fiat in order to provide a surface for retaining the ink and the purpose of this invention is to maintaln these inking surfaces in a flattened condition and cause them to be pressed firmly against the paper notwithstanding that the machine has been used a great length of time.

The platen die 4 is provided, from one end to the other, with projections 13 extendmg transversely of said platen die in parallel relation, having V-shaped cross sections and lying at angles corresponding to the oblique angles of the grooves in the printing characters. These projections correspond in width and height to the notches or grooves in the printing characters and are adapted to be received within such grooves to entirely fill the latter, forming with the same the means which ruptures or cuts the paper. Between the projections 13, the platen die is formed with flattened faces 14 which correspond in width to the width between the grooves or notches of the character die, so that the printing faces 12 of the characters will have a surface against which it may abut to firmly press the ink upon the paper.

From the foregoing it will be apparent that the character die and the printing die are so formed that one matches the other, that is, the printing die characters and the platen die have projecting surfaces and recesses which intermesh in such a manner that the paper is broken or ruptured while the ink is firmly pressed or squeezed against the paper, said ink passing through the ruptured portion and giving a clear character which cannot be obliterated.

What I claim as my invention and desire to secure by Letters Patent is:

1. The combination with a character die formed with projecting printing characters having flat ink-receiving faces and grooves,

I of a platendie having rupturing projections entering said grooves and entirely filling the same in order to force the ink into the ruptured edges of the paper and also having flattened portlons cooperating with flattened 3. The combination with a printing mem her having a plurality of' character dies thereon, each character die having its gharacters formed with flat ink receiving a aces and with grooves extendlng from one side of the character to the-other between the flat ink receiving faces and at an oblique angle to the height of the character of inking mechanism for the character dies, and a platen die having transversely extending projections adapted to be received within, and to fill entirely, the grooves of the characters and having also flattened faces between the projections to cooperate with the flattened faces on the character dies.

4. The combination with a printing member having a character projectin from the face thereof and formed wit parallel V-shaped grooves extending from one edge of the character to another and flat ink receiving faces between said grooves, of a platen die having parallel projections with -shaped cross sections arranged to be received within said grooves and entirely fill the same in order to force the ink into the ruptured edges of the paper and having flattened faces between the projections for cooperating with the flattened aces of the character, and inking means for inking the characters.
